I get the point(s) - I think, but. . .careers don't have to be within one company. And these days, they rarely are. Also, once you're a few years out from your multiple start-up jobs, you may see how some hard or soft skill you acquired has contributed/is contributing to your career progression. Several years ago, I looked around at my peers in my current job and thought. . .I really <i>was</i> on a career path (though it was not particarly planned and it spanned a number of organizations and industries); I really <i>do</i> have more breadth and depth of knowledge and experience than I thought; even though I feel that my talents are often wasted, I really <i>am</i> viewed as more senior than I thought (salary ranges here are an open secret, if you know how/where to look). . .
